Minnesota Vikings -- Korey Stringer told his wife the night before he collapsed that he had vomited and couldn't stop sweating. But Kelci Stringer said Korey insisted he was OK. In an interview with NBC's Today show host Katie Couric, her first since her husband's death from heatstroke Aug. 1, Stringer didn't lay blame on anyone for her husband's death. She did, however, urge coaches to adjust their training camp schedules to avoid extreme heat. "I think the routine that they have is OK," Kelci Stringer said. But she added that it wouldn't inconvenience teams to "change practice times to maybe earlier in the morning or late at night."
